Fatigue and Failure Analysis of Sandwich Composites using Two Types of Cross-Ply Glass Fibers Laminates and Epoxy Resin

Sandwich structures have become effective structural elements for engineering applications due to their good design flexibility. Understanding the material behavior under static and dynamic loads, as well as the failure mechanisms of these sandwich structures, is of great importance. This work evaluates the fatigue and static bending behavior of epoxy resin specimens and sandwich composites composed of an epoxy resin core with glass fiber laminated faces. The fatigue life, failure modes, and stiffness degradation of these specimens are determined experimentally. The specimens were cycled under constant amplitude and monitored by a data acquisition system that allowed continuous data collection. Three stages of failure were identified using microscope analyses and stiffness degradation curves. In the case of an imposed displacement of 2 mm, the sandwich structures were shown to have a significantly lower fatigue life than the epoxy resin specimens

Management of nitrogen fertilization in the succession black oat/corn in the no-tillage system

Os objetivos deste trabalho foram determinar, na sucessão aveia-preta/milho, a produção de matéria seca e o acúmulo de N pela aveia-preta e sua relação com a produtividade do milho em sucessão; a influência de épocas de aplicação de N sobre os teores de N no solo e a produtividade de grãos do milho. Os tratamentos foram: 15-0-20-55, 30-0-20-40, 45-0-20-25, 0-35-20-35, 0-70-20-0, 0-0-20-70 e 0-0-0-0, correspondendo, respectivamente, às quantidades de N (kg ha-1), aplicadas no perfilhamento da aveia-preta, na pré-semeadura, na semeadura e na cobertura do milho. O aumento na produção de matéria seca e de N acumulado pela aveia-preta, com as aplicações de N no seu perfilhamento, não alteraram a produtividade de grãos de milho. Apesar da aplicação de N em pré-semeadura do milho ter proporcionado maior teor de N no solo no início do desenvolvimento, a aplicação de N em cobertura propicia a obtenção de maiores produtividades de grãos.The objectives of this study were to evaluate, in the succession black oat/corn, the dry matter production and N accumulation by black oat and their corn productivity, the influence of applied N on soil N content and the best application time of mineral N for corn production. The treatments were: 15-0-20-55, 30-0-20-40, 45-0-20-25, 0-35-20-35, 0-70-20-0, 0-0-20-70 and 0-0-0-0, corresponding, respectively, to the amounts of N (kg ha-1) applied at black oat tillering, before corn seeding, at corn seeding and corn sidedress. The increase in the dry matter production and of N accumulated in the black oat, with the applications of N in the black oat tillering, did not affect corn grain productivity. Although the application of N before corn seeding provided greater soil N content at the beginning of corn development, the application of N as sidedress provided the highest corn grain yield

O uso do software Imagej na estimativa de substrato exposto pós controle de gramíneas invasoras

Species of the grass (Poaceae) have been recommended in initial recovery processes. However, they need a posterior control, avoiding the competition with those of interest, especially arboreal ones In this context, the objective was to quantify the exposed substrate in a degraded area in Diamantina, Minas Gerais, by of ImageJ software, on which different methods of weeding were applied for the control of exotic grasses Urochloa decumbes (Stapf) RD, Wabster and Melinis minutiflora P. Beauv. Control of grasses was carried out by applying different methods (chemical, manual and mechanical), distributed in 4 blocks, subdivided into plots and subplots. After 100 days, by means of ImajeJ processing images, it was observed that chemical method provided the lowest exposure of the substrate with greater presence of superficial biomass, unlike the manual method, which showed less vegetation cover. It was possible to quantify the substrate exposed in an environment with grass control, allowing effective planning of recovery techniques. The use of ImageJ was efficient, representing an alternative for the substrate quantification and several studies inherent in the analysis of vegetation coverage of degraded environments.Espécies de gramíneas (Poaceae) têm sido recomendadas em processos iniciais de recuperação. Entretanto, necessitam de um controle posterior, para evitar competição com espécies de interesse, especialmente arbóreas. Neste contexto, objetivou-se, por meio do software ImageJ, quantificar o substrato exposto em uma área degradada em Diamantina, MG, sobre a qual foram aplicados distintos métodos de capina para o controle das gramíneas exóticas Urochloa decumbes (Stapf) RD, Wabster e Melinis minutiflora P. Beauv.. Foi realizado o controle das gramíneas por meio da aplicação de diferentes métodos (químico, manual e mecânico), distribuídos em 4 blocos, subdivididos em parcelas e subparcelas. Após 100 dias, por meio de imagens processadas pelo ImajeJ, observou-se que método químico proporcionou a menor exposição do substrato e maior presença de biomassa superficial, diferentemente do método manual, onde houve menor cobertura vegetal. Foi possível quantificar o substrato exposto em ambiente com controle de gramíneas permitindo, de modo eficaz, o planejamento das técnicas de recuperação. O uso do ImageJ se mostrou eficiente, representando uma alternativa para a quantificação de substrato, e diversos estudos inerentes à análise de cobertura vegetal de ambientes degradados

Efficiency and accuracy of different ovulation inducers after progesterone device removal in crossbred multiparous cows

The aim of this study was to verify the efficiency and ovulation time after the administration of different inducers for synchronization of ovulation in beef cows. One hundred and eight non-lactating cows were distributed into the control group (CG; untreated; n=28), estradiol benzoate (EB) group (EBG; n=28); 17 beta-estradiol (17ßE) group (17ßEG; n=28), and deslorelin (DES) group (DESG; n=24). On day minus 11 (D-11) of the protocol, the CG underwent application of cloprostenol and ultrasound examination (US); on D0, progesterone (P4) was inserted plus EB; on D7, cloprostenol was applied; on D9, P4 was removed and cloprostenol plus 400 IU of equine chorionic gonadotropin (eCG) was injected. The EBG was subjected to treatment identical to that of the CG, except on D10, when the cows received EB. The 17ßE was subjected to the same protocol used in the CG except for the administration of 17ßE on D10. And, the DESG was subjected to the same treatment as the CG, except on D10, when the group received DES acetate. Twelve hours after the administration of EB, 17ßE and DES, ovarian US were performed every 6 hours. The preovulatory follicle (POF) diameters measured before ovulation were 19.5; 14.7; 18.7 and 19.8 mm respectively for CG, EBG, 17ßEG and DESG; and the time intervals between inducer application and ovulation were 20.2; 18.9; 21.0 and 22.5 hours respectively. In conclusion, all ovulation inducers were efficient in promoting ovulation; the inducers caused ovulation between 18.9 and 22.5 hours; EB promoted ovulation in a shorter time (P<0.05); 17ßE and DES showed greater variation in application/ovulation time between groups.

Optical Properties And Antiangiogenic Activity Of A Chalcone Derivate

Chalcones and their derivatives exhibit numerous pharmacological activities such as antibacterial, antifungal, cytotoxic, antinociceptive and anti-inflammatory. Recently, they have been assessed aiming for novel application in nonlinear optics and in the treatment of immune diseases and cancers. In this study, we investigate the optical properties of synthetic chalcona 1E,4E-1-(4-chlorophenyl)-5-(2,6,6-trimethylcyclohexen-1-yl)penta-1,4-dien-3-one (CAB7β) and its antiangiogenic potential using the chorioallantoic membrane (CAM) with the S180 sarcoma cell line. Experimental and theoretical results show intense absorption in the UVA-UVC region, which is associated with a π → π* transition with intramolecular charge transfer from the trimethyl-cyclohexen-1-yl ring to the chlorophenyl ring. Quantum chemical calculations of the first hyperpolarizability, accounting for both solvent and frequency dispersion effects, are in very good concordance with hyper-Rayleigh scattering measurements. In addition, two-photon absorption allowed band centered at 650 nm was observed. Concerning antiangiogenic activity, CAB7β causes a significant reduction in the total number, junctions, length and caliber of blood vessels stimulated by S180 cells reducing the presence of blood vessels, inflammatory cells and others elements related to angiogenic process. It is found that CAB7β is a versatile compound and a promising candidate for linear and nonlinear optical applications, in therapy against sarcoma and phototherapy
